“Because humans are complicated beasts, the monster said. How can a queen be both a good witch and a bad witch? How can a prince be a murderer and a saviour? How can an apothecary be evil-tempered but right-thinking? How can a parson be wrong-thinking but good-hearted? How can invisible men make themselves more lonely by being seen?

The answer is that it does not matter what you think, the monster said, because your mind will contradict itself a hundred times each day. You wanted her to go at the same time you were desperate for me to save her. Your mind will believe comforting lies while also knowing the painful truths that make those lies necessary. And your mind will punish you for believing both.”

This stopped him. Because they didn't, did they? That's one thing the monster had definitely taught him. Stories were wild, wild animals and went off in directions you couldn't expect.”

“And if one day,' she said, really crying now, 'you look back and you feel bad for being so angry, if you feel bad for being so angry at me that you couldn't even speak to me, then you have to know, Conor, you have to that is was okay. It was okay. That I knew. I know, okay? I know everything you need to tell me without you having to say it out loud.”

“You be as angry as you need to be,” she said. “Don’t let anyone tell you otherwise. Not your grandma, not your dad, no one. And if you need to break things, then by God, you break them good and hard.”

“Who am I? the monster repeated, still roaring. I am the spine that the mountains hang upon! I am the tears that the rivers cry! I am the lungs that breathe the wind! I am the wolf that kills the stag, the hawk that kills the mouse, the spider that kills the fly! I am the stag, the mouse and the fly that are eaten! I am the snake of the world devouring its tail! I am everything untamed and untameable! It brought Conor up close to its eye. I am thils wild earth, come for you, Conor O'Malley.

“Because I'm not blind to how Harry works, you know," she said. "A bully with charisma and top marks is still a bully." She sighed, annoyed. "He'll probably end up Prime Minister one day. God help us all.”

“There was once an invisible man, the monster continued, though Conor kept his eyes firmly on Harry, who had grown tired of being unseen.Conor set himself into a walk.A walk after Harry.It was not that he was actually invisible, the monster said, following Conor, the room volume dropping as they passed. It was that the people had become used to not seeing him."Hey!" Conor called. Harry didn't turn around. Neither did Sully nor Anton, though thet were still sniggering as Conor picked up his pace.And if no one sees you, the monster said, picking up its pace, too, are you really there at all?"HEY!" Conor called loudly.The dining hall had fallen silent now, as Conor and the monster moved faster after Harry.Harry who had still not turned around.Conor reached him and grabbed him by the shoulder, twisting him round. Harry pretended to question what had happened, looking hard at Sully, acting like he was the one who'd done it. "Quit messing about," Harry said and turned away again.Turned away from Conor.And then one day the invisible man decided, the monster said, its voice ringing in Conor's ears, I will make them see me."How?" Conor asked, breathing heavily again, not turning back to see the monster standing there, not looking at the reaction of the room to the huge monster now in the midst, though he was aware of nervous murmurs and a strange anticipation in the air. "How did the man do it?"Conor could feel the monster close behind him, knew that it was kneeling, knew that it was putting its face up to his ear to whisper into in, to tell him the rest of the story.He called, it said for a monster.”
